Application October 22, 1932, SeriaI No. 639,616 .1

14 Claims. (C 1. 220-54) a i application is a continuation in partof my application Serial #614,310, filedMay 31, 1932, for Cans, the subject matter thereof being embodied in this application. l

This inventionrelates to new and useful improvements in containersorcans and more particularly to an hermetically closed can provided with a rip strip for easy opening. 1

An object of the invention is to provide a can having score lines formed in the body portion adjacent the top end, providing a rip strip where by the top end may be" severed fromthe body portion, said end then-being adapted to serve as a reclosure cover for the can. A further object of theinvention is the pro+ vision of spaced'protuberances on the upper part of the sidewall of the can} by means of which frictional engagement is effected between the part of the sidewall remaining attached-to the top after the rip stripis removed and theupper por tion of the can sidewall. In one form, the protuberances are provided on the g 'upper portion of the sidewall of the can body below the score linesandthe cover is adapted to be sprung over said protuberances upon reclosure of the can. In

another form, the protuberances are provided above the score lines and form part ofthe cover when the rip strip is removed. 1 A still further object is to provide the reclosure cover with a substantially vertical annular wall, adapted to come in behind the upper portion of the can body when the rip strip is removed, said wall backing up said upper portion of the can body against inward pressure. A feature of the can is the provision of a temporary paper collar or collar of other suitable material; said collar extending behind the score lines, so that whenthe rip strip'is tornoif, the contents of the can will be prevented from overflowing. A gasket is also provided outside the annular wall of the top to ensure a tight reclosure. In my preferred form the diameter of'the top of the can body equals that of the lower portion of saidbody. I

Other objects and advantages'willbecome ap: parent upon a further study of the description and-drawings, in which:-- c l Fig. 1 is a cross section of one type of my can before being opened, said type being one in which the protuberances are below the score lines.

, Fig. 1A is an enlarged section of annppercorner of the can, of the type of Fig. 1,but with the addition of a gasket outside the annular wall.

Fig.6 is a modified form of the reclosure cover of the can, in which the depressed portioncomprises substantially the entire top wall of the can.

Fig. 6 shows anothermodified form of reclosure cover." I

Fig. 7 is anjenlarged section of an upper corner of the can of the type in which the protuberances areabove thescore line, and the diameter of the upper portion of the can body is equal that-of the lower portion. l j

Fig. 8 is an enlairgedsection' of an upper corner of the-can, of the type of Fig. '7, with the reclosureseparated from the can by the depth of the rip strip. l

Fig. 9 is an enlarged section 01' anupper'corner of the canfof the typeof Fig. 7 ,-with the reclosurecover shown reclosing the can. t c

Fig. 10 is an enlarged section of an upper corner of the can, of the type of Fig. 7, but with the addition of a temporary insidecollar, and i Fig. 11 is an enlarged section of an upper corner of the can, of the type of' Fig. "I, but with the addition ot-a gasket outside the annular wall. The canincludes'a body portion 6. An encir cling ripstrip I is formed in the body'by means of parallel'scorelines 8 and 9; A tongue I is provided at one end of rip strip 1. Protuberances H are spaced in a row about the side of the can just-below score'line 8. A;bead 'I2 is provided in body portion 6 just below the row of protuberances I l for stifiening the upper part of the body portion; Top wall [3 is fastened to the sidewall of the canby a'seam I45 Froni the top of bead l2 to* seam" H, the sidewall ofthe can inclines outwardly so thatwhen ripstrip I is torn art, the lower edge of the top at what was score line 9 has a diameter "sufliciently great to pass over the upper edge of the body portion at what was score line 8. The diameter of score line 9, however, is le'ss than the diameter ofa cylinder which would circumscribethe protuberances. The cover has a downwardlyj extendinglannular bead; l formed intoriwall 13; The outer and upwardly extending wall l6 heme I5 -is adapted to come insidethe bodyportion '6 above-bead I2 and just behind protuberances I L;

ably comes below-or is recessed below seam H1 Top wall I 3 prefer a other grip being between wall l6 and the metal,

around the back of and between said protuberances. protuberances II is reinforced by .thehooking action of said latter wall over saidprotuber ances. Where a gasket asat 30; Fig. lAcis used against wall l6, as will be explained later, the friction grip with wall I 6 takes place through said gasket. Bead l2 .stifiensthe can just below the protuberancesand at the sametime protects the hand.- from the bottom edge. of wall l 1. when the can is reclosed. 'I?l1e modified. form oil he cover shown in Fig. 5, has no bead I-5,.but instead substantially the entire top wall is depressed so as tozgive rise to an annular-wall lfi extending in-an up and down direction.- 7 I I i ,Fig. fifshows a substantiallyflush top wall having an annular depression l8 formed therein, giving rise to the substantially vertical: wall I 5. In Figs. 7, 8 and 9 is shown a modified form of can. ,Here the can. body l9=has a row-.ofspaced protuberances v20 in its ,sidewalL; located above scorelines 2l and 22 of rip strip 25.; Protuberanees 20 extend in the; opposite; direction from protuberances H of Fig. 1. The outside diameter of; the can body, at the-top,edge.23, does not exceed that of the lower. portion of the can body, that is the;.portion of the can body below neck 24. The upper portion of the can sidewall slopes outwardlybetween the smallest diameter at neck to; the top; edge 23. ,The-slope is, such,. that when rip strip -25 .istorn ofi, the. lower edgeof the top at what :was score line. 2| has a diameter sufiicientlyvgreat to pass-.over the upper edge of the body portionatwhatwas-score line 22. The diameter of'scoreline 22, however, is greater than the diameter of a cylinder which would be, inscribed within protuberances 20... The. cover has a downwardlyextending. annular bead 26 formed in top wall 21.- flhejouter and upwardly.extend-.- ing annularwall 28, ofbead26,-:isadapted to come inside the sidewall: of cam-body 19 above neck 24.; Wall. 28 extends down far enough below edge 23= to come opposite -,protuberances 20. Similar variations can be madein the cover of Fig. 7 as those-shown in Figs. 5 and 5 When the can is reclosed by, the, cover after severingrip strip 25. protuberances 20- onthe portion-of the sidewall remaining attached to the cover are. sprung. over the portion of the. sidewall of thecan. bodyremaining above neckl24 said latter portion of .the .sidewall also being sprungand having a hooking action over protuberances 20; At, the same time," substantially vertical wal; l -28 comes behind the portio'nLof the sidewall remaining aboveneck .24 and backsit up againstztheyinward pressure of protuberances 20. A double friction grip isobtained bythe cover on thekbodyportion, one. grip being; between the ,protuber-ances and the-sidewall of the. body portion above; neck 24; and .the ,othergrip being; between saidsprotuberancesjandawall 28w The latter. fric:

The friction grip between wall I! and,

the can is reclosed by the cover after sevtion grip is reinforced by the hooking action over protuberances 28 as noted above, especially when a gasket 30, Fig. 11, is used around the outside of wall 28. Where gasket 3|] is used, the friction grip with wall 28 takes place through said gasket.

The portion of the sidewall, extending from neck 24 down to the full diameter of the can, acts to stiffen this portion, and to protect the hand from the lower edge of the sidewall of the cover. In order to prevent the spilling of the contents of the can when the rip strip-25 is'tornofi, I prefer toprovide' (Fig; 10) behind the rip strip a temporary collar 29 of suitable material. The lower portion of the collar is turned outwardly and downwardly from neck 24 to the full diameter of the can below., A temporary collar, similar to the one just'described, can be used for the type of can of Fig. 1, as well. When suflicient of the contents of the can have been used, collar 29 can be removed. Foradditional tightness of ,reclosure, I prefer to use agasket 30 (Fig..,11) located around the outside of annular wall 28. -When rip strip 25is removed and the can reclosed, gasket 3ll-comes inside-of. theportion of thecan'sidewall remaining above neck; 24. Ina-similar. manner, agasket 30. can be-used around the annular wall It-of Figs. 1 to 6 inclusive. I claim: I I.
